Using a WS2812B LED ribbon with Arduino

Using a WS2812B LED ribbon with Arduino

LED ribbons are made up of a succession of addressable RGB LEDs, i.e. the brightness and colour of each LED can be set independently. There are several ribbon models: single colour, non-addressable, 5 or 12V, etc. Pay attention to the model you want to use. Hardware...
Using a multiplexer with Arduino

Using a multiplexer with Arduino

The multiplexer is an integrated circuit made up of logic circuits allowing several signals to be concentrated on the same output (mutiplexing or mux) or to connect an input to one of its N outputs (demultiplexing or demux). In this tutorial, we will see the use of...

Using a shift register with Arduino

The shift register is an integrated circuit consisting of logic circuits in series that can store high or low states. It can be used to drive LEDs or to retrieve the state of several sensors. Hardware ComputerArduino UNOUSB cable A Male to B MaleShift Register 74HC595...
Luminosity measurement with a photoresistor

Luminosity measurement with a photoresistor

A photoresistor is an electronic component that measures ambient light. This component is useful in some projects such as a solar panel light follower or home automation to create a smart lamp that only turns on when it is dark or to set up an alarm with a laser...
Create a component in Fritzing

Create a component in Fritzing

When working on an electronics project, it’s a good idea to put your ideas on paper to make sure you do not forget anything before implementation. This allows you to verify the concept and to share a clear representation of your work with other interlocutors...
